Climate Crisis: London’s River Village and Pools

https://i0.wp.com/i.telegraph.co.uk/multimedia/archive/02192/london-from-space_2192333k.jpgOne of the greatest challenges facing future urban planning is the very real prospect of running out of land. In addition to urban sprawl encroaching on neighboring farmlands, the concentration of people at the core eventually creates a situation where open spaces become incredibly scarce. Luckily, the city of London – one of the largest and most densely populated cities in the world – is coming up with some innovative solutions.

For starters, the city is developing the area around some former dockyards in East London to accommodate a floating neighborhood. Borrowing from similar projects that were initiated in the Netherlands to prepare for rising sea levels, London’s new river-based housing program is designed to place housing in the one spot that hasn’t been converted to high-rise apartments or suburban dwellings.

A floating walkway will lead back to land, where the city plans a much larger development with tens of thousands of new homes.

Earlier in its history, the area, known as the Royal Docks, served hundreds of cargo and passenger ships each day. The three docks were the largest enclosed docks in the world – 250 acres of water and over 1000 acres of land – and got more use than any other port in London. But they haven’t been in use for the last several decades, and that’s why the city wants to transform the area.

With demand for new homes in London soaring, we need to put every scrap of available land to the best possible use. Tens of thousands of new homes, workspace, leisure, and cultural facilities are being developed . . . The ‘Floating Village’ will be yet another draw, restoring London’s docklands to their former glory as a centre of enterprise and bringing jobs, growth, homes and visitors.

On the same front, the city of London is also contemplating turning its river waters into a massive public pools project. Known as the Thames Bath Project, this idea was inspired by similar ideas where swimming pools have been created out of waterways. For example, New York has a project called +Pool, which has raised more than $300,000 in crowd-funding, and looks set for a 2016 launch.

https://i0.wp.com/h.fastcompany.net/multisite_files/fastcompany/imagecache/inline-large/inline/2014/08/3034656-inline-i-1-london-joins-list-of-cities-building-pools-in-their-rivers.jpgThe Thames Baths Project is similar, aiming to create a freshwater lagoon amid the meandering old waterway. The consortium responsible consists of Studio Octopi, Civic Engineers and Jonathan Cook Landscape Architects, all of whom won the competition last year to come up with new river uses. Initially, they hoped to create a pool using water from the Thames that would be filtered and treated.

However, that plan has since been updated and improved to something a little more sanitary. Now, they plan to pump in freshwater, rejected the New York City idea of filtering the water as it enters the pool space because of the concern of sewage. And though London has a major sewage system upgrade planned, the designers are worried it won’t be ready in time to ensure sufficient water quality.

london-poolAs Chris Romer-Lee, director of Octopi, explained:

We’re using freshwater because of the sewage overflows from the aging [Sir Joseph William] Bazalgette sewers. They dump millions of tons of sewage into the river after even the shortest rain storm. A filtration system could work. We’ve been looking at natural swimming pools and the filtering systems they use. But the +Pool filtering system is as yet unproven.

The design calls for floating pontoons with space for three pools –  one large, one medium, and one for paddling. A thick layer of vegetation will mark the edges and a ramp leading off the side will connect swimmers back to firm ground. The $8.5 million plans are still awaiting approval from the city, but, if all goes well, the baths could be completed sometime early in the next decade.

london-pools1The purpose, according to Romer-Lee, is about re-purposing something that would otherwise be forgotten:

We need these baths to reconnect Londoners with their largest public space. The river is used extensively for transporting building materials, passengers and the like but is increasingly becoming something that Londoners look over and don’t engage with.

Meanwhile, Berlin also has a proposal for an open river pool, as does Copenhagen, which actually already has swimming in its harbor. No doubt, it won’t be long before others follow. In fact, the idea of re-purposing public spaces that have fallen into disuse is becoming increasingly popular – not just as a response to sprawl, but as an innovative solution of what to do with infrastructure that has fallen into disuse.

Cities like Detroit, Philadelphia, Washington DC and Hamilton, Ontario and Montreal, Quebec – just to name a few – all might want to consider getting on board with this…

Immortality Inc: Regrowing Body Parts

https://i0.wp.com/images.gizmag.com/hero/lizardtails-2.jpgAnyone who has ever observed a lizard must not have failed to notice that they are capable of detaching their tails, and then regenerating them from scratch. This propensity for “spontaneous regeneration” is something that few organisms possess, and mammals are sadly not one of them. But thanks to a team of Arizona State University scientists, the genetic recipe behind this ability has finally been unlocked.

This breakthrough is a small part of a growing field of biomedicine that seeks to improve human health by tampering with the basic components (i.e. our DNA). The research, which was funded by grants from the National Institutes of Health and Arizona Biomedical Research Commission, also involved scientists from the University of Arizona College of Medicine, Translational Genomic Research Institute, and Michigan State University.

dna_cancerAccording to Prof. Kenro Kusumi, lead author of a paper on the genetic study, lizards are the most closely-related animals to humans that can regenerate entire appendages. They also share the same genetic language as us, so it’s theoretically possible that we could do what they do, if only we knew which genes to use and in what amounts. As Kusumi explains in the paper, which was published Aug. 20 in the journal PLOS ONE. :

Lizards basically share the same toolbox of genes as humans. We discovered that they turn on at least 326 genes in specific regions of the regenerating tail, including genes involved in embryonic development, response to hormonal signals, and wound healing.

Other animals, such as salamanders, frog tadpoles, and fish, can also regenerate their tails. During tail regeneration, they all turn on genes in what is called the ‘Wnt pathway’ — a process that is required to control stem cells in many organs such as the brain, hair follicles and blood vessel. However, lizards have a unique pattern of tissue growth that is distributed throughout the tail.

calico-header-640x353 It takes lizards more than 60 days to regenerate a functional tail — forming a complex regenerating structure with cells growing into different tissues at a number of sites along the tail. According to Katsumi, harnessing this would be a boon for medicine for obvious reasons:

Using next-generation technologies to sequence all the genes expressed during regeneration, we have unlocked the mystery of what genes are needed to regrow the lizard tail. By following the genetic recipe for regeneration that is found in lizards, and then harnessing those same genes in human cells, it may be possible to regrow new cartilage, muscle or even spinal cord in the future.

The researchers also hope their findings will also help repairing birth defects and treating diseases such as arthritis. Given time, and enough positive results, I think it would be fair to expect that Google’s Clinical Immortality subsidiary – known as Calico – will buy up all the necessary rights. Then, it shouldn’t be more than a decade before a gene treatments is produced that will allow for spontaneous regeneration and the elimination of degenerative diseases.

The age of post-mortal is looming people. Be scared/enthused!

Ending Parkinsons: Wearables and Cloud Storage

parkinsonsBehind Alzheimer’s, Parkinson’s disease is the second-most widespread neurodegenerative brain disorder in the world, and affects one out of every 100 people over the age of 60. After first being described in 1817 by Dr. James Parkinson, treatment and diagnosis have barely changed. Surgery, medications, and management techniques can help relieve symptoms, but as of yet, there is no cure.

In addition, the causes are not fully understood and appear to vary depending on the individual. But measuring it is often a slow process that doesn’t generate nearly enough data for researchers to make any significant progress. Luckily, Intel recently teamed up with the Michael J. Fox Foundation to and have proposed using wearable devices, coupled with cloud computing, to speed up the data collection process.

apple_iwatch1Due to the amount of variables involved in Parkinson’s symptoms — speed of movement, frequency and strength of tremors, how it affects sleep, and so on — the symptoms are difficult and tedious to track. Often, data is accrued through patient diaries, which is a slow process. Intel’s plan, which will involve the deployment of smartwatches, can not only increase the rate of data collection, but detect a much higher volume of variables and frequency than a personal diary could.

It is hopes that they will be able to record 300 observations per second, thus creating a massive amount of data per patient. The use of wearables means that the data can even be reported and monitored by researchers and doctors in real time. Later this year, the MJFF is even planning on launching a mobile app that adds medication intake monitoring and allows patients to record how they feel, making personal diaries easier to create and share.

cloud-serverIn order to collect and manage the data, it will be uploaded to a cloud storage data platform, and has the ability to notice changes in the data in real time. This allows researchers to track the changes in patient symptoms and share from a large field of data to better spot common patterns and symptoms. In the end, its not quite a cure, but it should help speed up the process of finding one.

Wearable technology, cloud computing and wireless data monitoring are the hallmarks of personalized medicine, which appears to be the way of the future. And while the concept of metadata and keeping medical information in centralized databases may make some nervous (as it raises certain privacy issues), keeping it anonymous and about the symptoms should lead to a speedy development of treatments and ever cures.

News From Mars: Mysterious “Thigh Bone” Revealed!

mars-thigh-bone-illusion-curiosity-photoTwo weeks ago, the Curiosity rover spotted an object on the surface of Mars that bore a striking resemblance to a femur (aka. athigh bone). This sighting caused a bit of a media stir and fueled speculation – mainly by conspiracy and UFO theorists – that proof of life on Mars had finally been found. This claim was quickly picked up by media outlets and began to spread like a bad strain of flu.

Alas, NASA has since announced that the finding, much like the Martian “donut” and “rat”, was just another piece of oddly-shaped rock. Mission scientists believe that here too, the rock was sculpted into its unusual shape by wind or water erosion. NASA announced all this when they released Curiosity’s “thigh bone” photo with a science explanation on Thursday (Aug. 21). In the caption, they said that:

No bones about it! Seen by Mars rover Curiosity using its MastCam, this Mars rock may look like a femur thigh bone. Mission science team members think its shape is likely sculpted by erosion, either wind or water.

If life ever existed on Mars, scientists expect that it would be small simple life forms called microbes. Mars likely never had enough oxygen in its atmosphere and elsewhere to support more complex organisms. Thus, large fossils are not likely.

MARS-COMET-surfaceIn short, the long-sought after signs of life that NASA is searching for have yet to be found. The Curiosity rover has found evidence that Mars was once a habitable place in the ancient past, mainly by determining with certainty that it once held water and a viable atmosphere. However, to date, there is no evidence that creatures large enough to leave a bone behind ever existed on the planet.

There is a long tradition of seeing shapes in Mars rocks that don’t reflect reality. The phenomenon in which the human brain perceives faces, animals or other shapes that aren’t really there is known as pareidolia; and when it comes to Mars, there is a long and fertile history of this taking place. In fact, in 1877 when astronomer Giovanni Schiaparelli looked up at Mars when it was in opposition, he spotted a network of lines that ran along the planet.

martian_canalsLater astronomers confirmed these sightings and erroneously thought them to be canals, an observation which was quickly seized upon by the popular imagination and spawned an entire mythos of there being a civilization on Mars. This civilization, made up of little green men known as Martians, is the entire basis of alien mythology which would go on to inspire 20th century works as The War of the Worlds and The Martian Chronicles.

And for those old enough to recall, the “Martian face”, which was captured by the Viking Orbiter in 1976, is a more modern example. As you can see from the picture below (lower right hand), the low-resolution photos of the Cydonian mesa led many people to see a human face in it. This led to much speculation and more than a few crackpot theories about a civilization on Mars.

mars_faceHowever, high-res photos taken in 2001 by the Mars Global Surveyor probe (center) put these claims largely to rest by showing that the “face” was just an optical illusion. However, many of these same theorists moved on to claim that pyramid-like formations in that same region (Cydonia) so closely resembled those of Giza that there had to be a common explanation – i.e. aliens built the pyramids.

And in all cases, the golden rule seems to apply: never let little a thing like the facts or plausibility get in the way of a good story! As the rover continues on its long mission to find evidence of life on Mars, I am sure there will be plenty more pictures being seized upon by oddball theorists who are looking to peddle their oddball theories. Some of them are sure to be entertaining, so stay tuned!

Settling Mars: The Mars Base Challenge 2014

mars-colonyLife on Mars can’t become a reality without some serious design concepts and engineering. And that’s why Thingiverse, in cooperation with NASA’s Jet Propulsion Laboratory, conduct the Makerbot Mars Base Challenge every year. Taking Mars’ extreme conditions into consideration, people are tasked with designing a utilitarian Mars base that can withstand the elements and make settlers feel at home.

The competition opened on May 30th and received some 227 submissions. The challenge brief asked entrants to take into account the extreme weather, radiation levels, lack of oxygen and dust storms when designing their Martian shelters. And the winning entries will each be awarded a MakerBot Replicator 2 Desktop 3D Printer in order to help them fully explore their designs for Martian abodes.

And although the applicants did not always nail the science, their designs have a novelty that has not been seen in some time. This can especially be seen in with this years finalists, which included a design for a Martian pyramid, a modular beehive and a three-tiered Acropolis.

MarsChallengeResultsThe Thingiverse community appears to have been hugely supportive, printing out the designs themselves and offering handy hints in the comment section beneath each entry. Some were dismissed for being impractical; for example, those that would be immediately flattened or kill all of its inhabitants if it were installed on the Martian surface. But one designer, Noah Hornberger, points out:

A toy car does not need fuel because it runs on the imagination of the child who drives it around. So it seems to me that I’m driving my toy car at full speed and you are here telling me what kind of fuel and oil it needs to run. I would rather leave the physics to the right people.

Luckily, that’s what NASA is on hand for – to ensure that it’s not just the mathematicians and engineers that have an interest or a say in our Martian future, but to make sure those designs and dreams that come from the public meet the basic scientific and engineering requirements. Bringing together inspired ideas and realistic needs, here’s how this year’s finalists measured up.

MarsPryamid-4_Feature_preview_featured This Mars structure is designed with resource consumption and allocation in mind, and also takes into account that the majority of activity would be taking place inside the structure rather than outside. As its creator, Valcrow. explained:

High traffic rooms all have ample natural Martian light to help with the crews extended isolation and confinement… This design focuses on looping essential systems into as many multi-functional roles as possible to ensure that the very limited resources are used and reused as much as possible.

This includes food created through a sustainable aquaponics system which would sit at the top of the pyramid, where it can get some light. A mirror-based series of solar panels will be responsible for collecting energy, with a nuclear generator for backup, and water would be stored near the main power center so that it heats up. The whole thing is inspired by the Pyramid of Giza, but unlike that beauty it can be reconfigured for science or engineering tasks and experiments.

Mars_beehiveThis second design, known as the Queen B because of its modular beehive configuration, comes with all the mod cons and home comforts you might expect on Earth – a kitchen, two bathrooms, a garden, and a 3D print lab and decompression room. Its creator, Noah Hornberger, chose a flat-panelled, low-level design that would be cheap and easy to build and allow for less heat energy to be lost. The hexagon shape was chosen for its durability and ability to form modular designs.

Depleted uranium would be used to create laminated panels that would shield out the elements, but would need to be sandwiched between other materials to make it safe for the occupants. An exothermic chemical reactor would meanwhile be used to heat an underground water container, which will provide heat for the basecamp. Excess steam could also power generators to supplement solar power.

Speaking on behalf of his creation, Hornberger said:

I have extrapolated on the idea of a fully functional apartment on Mars with all the modern amenities fitted inside 16-foot-diameter hexagons. I think that to present Mars life to people and actually make it appealing to the public it needs to feel like home and reflect the lifestyle trends of Earth living.

Mars_acropolisAnd last, but not least, there’s the Mars Acropolis – a design that blends materials used here on Earth to create a classic futurist design that looks like it would be at home in the classic Fritz Lang film. Concrete, steel and Martian soil help form the outer wall that protects the population, while carbon fibre, stainless steel, aluminium and titanium would be used to build the main body.

Three greenhouses contain the vegetation and help filter the air and produce oxygen, and there are decompression chambers at the entrance. On level two, residents can park their shuttles before entering the living quarters and labs, while level three acts as the nerve center – with flight operators and observation posts. It’s joined by a huge water reservoir that flows to the first level for purification.

Designer Chris Starr describes the layout as follows:

The structure serves as a mass research facility, to explore and develop means for additional colonization of the planet. Due to the water vapour contained in the Martian atmosphere, that vapour can be harnessed into usable liquid water, where the condensation is collected from the water vapour, which is filtered back into the reservoir.

mars_one2In all cases, the designs draw attention to the fact that any structures intended for life on Mars will have to achieve a balance between resource management, comfort and entertainment, and security against the elements. At this point, there’s no telling exactly what a Martian settlement will look like; but as always, the truth will likely be stranger than fiction.

Powered by the Sun: Breakthrough Solar Cells

solar1In addition to becoming cheaper, and increasing in efficiency and yields, solar cell technology is also growing in terms of innovative design. By going beyond the conventional design of silicon panels and electrical cables, researchers are ensuring that solar technology can go farther. And the latest advances in design are especially far-sighted, aiming to merge solar technology with just about any surface, and even sending it into space.

In the former case, researchers at Michigan State University have created a fully transparent solar concentrator, which could turn any window or sheet of glass – from highrise buildings to the screens on smartphones and tablets – into a photovoltaic solar cell. And whereas other “transparent” solar panels have been designed in the past, this one is the first that truly lives up to the word.

transparent-solar-cellScientifically, a transparent solar panel is something of an oxymoron. Solar cells, specifically the photovoltaic kind, make energy by absorbing photons and converting them into electrons. If a material is transparent, by definition it means that all of the light passes through the medium. This is why previous transparent solar cells have actually only been partially transparent, and usually cast a colorful shadow.

To get around this limitation, the Michigan State researchers use a slightly different technique for gathering sunlight. Instead of trying to create a transparent photovoltaic cell, they used a transparent luminescent solar concentrator (TLSC), which consists of organic salts that absorb specific non-visible wavelengths of ultraviolet and infrared light, which they then luminesce (glow) as another wavelength of infrared light (also non-visible).

https://i0.wp.com/www.extremetech.com/wp-content/uploads/2014/08/transparent-luminescent-solar-concentrator-colorful.jpgThis emitted infrared light is guided to the edge of plastic, where thin strips of conventional photovoltaic solar cell convert it into electricity. Currently, the Michigan TLSC has an efficiency of around 1%, but they think 5% should be possible. On their own, these aren’t huge figures, but on a larger scale — every window in a house or office block — the numbers quickly add up to a significant electrical yield.

Moreover, the researchers are confident that the technology can be scaled all the way from large industrial and commercial applications, down to consumer devices, while remaining “affordable.” So far, one of the larger barriers to large-scale adoption of solar power is the intrusive and ugly nature of solar panels. But if large amounts of solar power can be produced from sheets of glass and plastic, it would go a long way to making the scaling process feasible.

solar_panel_origamiAnother major innovation comes from Brigham Young University, where researchers have been working with NASA’s Jet Propulsion Laboratory to address the challenge of Space-Based Solar Power. For some time, scientists have understood that a solar array in orbit of Earth would be ideally suited for solar power collection, since it would be immune to weather, cloud cover or diurnal cycles (aka. nighttime).

Unfortunately, getting solar cells into space is a bit of a problem. In order to be effective, solar panels need to be thin have a large surface area to soak up more rays. This makes it difficult to transport them into orbit, and requires that they be broken down,and flown up piece by piece, and then assembled once in orbit. Given the cost of mounting a sending a single rocket into orbit, this prospect becomes very costly very fast.

solar_panel_origami1However, the Brigham team came up with a simple and elegant solution to this problem, and found it in the form of origami. By working with complex origami folds, they were able to design a solar array that can shrink down to one-tenth of its original size. Folded up, the device is 2.7 meters (8.9 feet) across and can easily wrap around a spacecraft. Once it reaches space, the array would then unfold to become as wide as 25 meters (82 feet).

Given that solar panels deal with large, flat, thin structures, the origami concept seems like a natural fit. And this is not the first time that it has been used in space equipment design – in the 1990’s, Japanese astrophysicist Koryo Miura created a prototype for another folding solar panel. However, that project was abandoned for various reasons, not the least of which was lack of funding.

space-solar-headTo make the concept work and renew interest in the application, he Brigham team worked with Robert Lang, a world-renowned origami expert who also happens to be a mathematician and engineer and once worked at JPL himself. As Brian Trease, a mechanical engineer at the Jet Propulsion Laboratory, said:

He was trained as a physicist, used to work at JPL, and then got tired of the formal bureaucracy and left to start folding paper. Now he’s a world expert… We see value in going directly to any artist, even if they don’t have his credentials, because they have the thousands of hours or folding and tinkering to realize what can and can’t be done. Anytime you can bring in other disciplines, they just visualize things differently and bring in different solutions to your problems.

The new solar panels could be used to power spacecraft and potentially also on orbiting power stations that could wirelessly send energy to Earth via microwaves. A similar design could also be used on Earth to provide new options for portable solar power in remote locations. The same type of design might also be used in architecture or product design because of its unusual looks and function.

NASA_suntowerAccording to Trease, the Department of Defense has already been in touch with them regarding applications for soldiers in the field:

Soldiers right now might carry around 100 pounds, 15 of those pounds are batteries and fuel. If you can eliminate that, you’ve dramatically reduced their load… It’s different from opening an umbrella, because it can accommodate rigid material. You could do something like a deployable glass chandelier or a table. When it’s deployed, it looks like a flower blooming–it’s got a nice aesthetic to it.

In the next few weeks, Trease will also meet with other experts to consider different potential applications for space equipment, like antennas and reflectors, that could also deploy using origami. And given the rapidly-dropping prices associated with placing objects into orbit, this could prove to be the basis for the dream of Space-Based Solar Power – where all our energy needs are met by solar arrays in orbit that then beam them to Earth.

Cyberwars: The Month of Cyberattacks

hackers_securityThe month of August has been a busy time for online security specialists, due to numerous cyberattacks being reported close to each other. First came word that supermarket chain Supervalu had been hacked, followed by news of security breaches at a largest American medical group, the Nuclear Regulatory Commission and then the UPS Store. In all cases, the intrusions led to the theft of millions of users’ personal data.

The worst of the lot appears to have been the massive cyberattack on Community Health Systems, one of the largest hospital chains in the US that oversees 206 hospitals in 29 states. According to the company, the intrusion led to stolen Social Security numbers, patient names, addresses, birth dates and telephone numbers of some 4.5 million patients. And as usual, the attack is believed to have had the backing of a foreign government.

https://i0.wp.com/www.chs.net/wp-content/uploads/2013/12/hma-map.pngThis is the largest known attack to involve hospital patient information since the US government began tracking these types of data breaches in 2009. According to Elysium Digital data security expert Joseph Calandrino:

One possible goal of this attack is to facilitate future targeted attacks. The type of data that was stolen from the hospital system is often used to verify a person’s identify. The exposure of this data creates a risk that the hackers could leverage it to gain access to other accounts and information.

As is so often the case these days, it is believed the cyberattack originated in China. Security firm Mandiant, which investigated the breach in April and June, said the hackers belong to a group that targets crucial infrastructure, such as defense, engineering, financial services, and health care companies. It’s unclear if these hackers are affiliated with the Chinese government.

Unit-61398-Chinese-Army-Hacking-Jobs-With-Great-BenefitsVarious security experts have long accused China of waging a cyberwar on US government and private company websites. For example, a report that was released by Mandiant back in 2013 linked Unit 61398 of the China’s People’s Liberation Army to a large number of cyberattacks on US soil. However, the Chinese government has flatly denied that it is involved in cyber-espionage or hacking.

Community Health Systems has since reported that it stopped the cyberattack by removing the malicious software used by the hackers and is notifying its patients of the breach. It has also been reported that the hack may have been facilitated by the Heartbleed bug, a flaw in OpenSSL that hackers use to exploit to obtain encrypted data. The timing certainly seems apt, as the bug was revealed back in April and the attack took place between April and June.

nsasecurity_primary-100041064-largeHowever, this was were merely one of several breaches that took place over the past few months. In addition to the CHS, UPS, and numerous major outlets, cybersecurity firm Hold Security identified what was arguably the largest known data breach in history earlier this month. In this attack, the Russian cybergang Cybervor allegedly stole 1.2 billion username and password combinations and more than 500 million email addresses.

With these latest attacks, it appears that large-scale security breaches carried out by individual hackers and sponsored by nation-states is becoming the new normal. And as these kinds of attacks become more common, cybersecurity experts are concerned that people may suffer from “alert fatigue”, where they will basically cease caring about and not be aware of breaches that affect them.

RAND_hqIn addition, security experts would like people to keep in mind that there is a difference between a spike in activity and reporting on activity. Much like the problems of violence, teen sex and crime rates, there is likely a gap between an actual increase and the perception of one. As Lillian Ablon, a researcher for the RAND Corporation, explained:

Back during Operation Aurora [in 2009], when Google got hacked, Google coming out [in 2010] was a big step in the industry. Before that, companies didn’t really talk about being breached.

Legally, companies and government agencies are required to report security breaches to the public only when customer data is involved, and only in 47 states. Alabama, New Mexico, and South Dakota lack mandatory reporting laws, and few laws on the books extract penalties when a breach occurs. Still, whatever the magnitude of the number of security breaches, it’s also true that we are living in an increasingly uncertain world when it comes to keeping our data safe.

internetNaturally, public vigilance is a good policy, but its not exactly a solution. When the hacks at the Nuclear Regulatory Commission, the Community Health Systems, the Cybervor attack, and hack of the DHS, the attacks were suspected of coming from abroad. More and more, attacks are being staged from a location that is far removed from the source, and backed by third parties who are likely unknown.

Security experts believe that the eventual solution will require businesses to rethink how they operate, putting a much bigger emphasis on security. But the consequences of that could have global economic implications, if better security hurts competitiveness. In the short term, it means that customers who do business with companies that suffer security breaches will need to be that much more vigilant.

That means not reusing passwords for multiple accounts, using two-factor authentication when available, and keeping a close eye on bank statements and credit card activity. And as for the breaches themselves, there’s not much you can do except be prepared to hear about more of them, more often. For better or for worse, it is the age we live in, where big data means big data intrusion!

Universe Today: Are Intelligent Civilizations Doomed?

Gaia_galaxyMy friend over at Universe Today, Fraser Cain, has been busy of late! In his latest podcast, he asks an all-important question that addresses the worrisome questions arising out of the Fermi Paradox. For those unfamiliar with this, the paradox states that given the age of the universe, the sheer number of stars and planets, and the statistical likelihood of some of the supporting life, how has humanity failed to find any indications of intelligent life elsewhere?

It’s a good question, and raised some frightening possibilities. First off, humanity may be alone in the universe, which is frightening enough prospect given its sheer size. Nothing worse than being on a massive playground and knowing you only have but yourself to play with. A second possibility is that extra-terrestrial life does exist, but has taken great pains to avoid being contacting us. An insulting, if understandable, proposition.

alien-worldThird, it could be that humanity alone has achieved the level of technical development necessary to send out and receive radio transmissions or construct satellites. That too is troubling, since it would means that despite the age of the universe, it took this long for an technologically advanced species to emerge, and that there are no species out there that we can learn from or look up to.

The fourth, and arguably most frightening possibility, is the Great Filter theory – that all intelligent life is doomed to destroy itself, and we haven’t heard from any others because they are all dead. This concept has been explored by numerous science fiction authors – such as Stephen Baxter (Manifold: Space), Alastair Reynolds (the Revelation Space universe) and Charles Stross (Accelerand0) – all of whom employ a different variation and answer.

kardashev_scaleAs explored by these and other authors, the biggest suggestions are that either civilizations will eventually create weapons or some kind of programmed matter which will destroy – such as nuclear weapons, planet busters, killer robots, or nanotech that goes haywire (aka. “grey goo”). A second possibility is that all species eventually undergo a technological/existential singularity where they shed their bodies and live out their lives in a simulated existence.

A third is that intelligent civilizations fell into a “success trap”, outgrowing their resources and their capacity to support their numbers, or simply ruined their planetary environment before they could get out into the universe. As usual, Fraser gives a great rundown on all of this, explaining the Fermi Paradox is, the statistical likelihood of life existing elsewhere, and what likely scenarios could explain why humanity has yet to find any proof of other civilizations.

The Future is Here: Cancer Drug Developed by AI

AI'sThe development of cancer drugs is a costly, expensive, time-consuming process that has a high probability rate of failure. On average, it takes 24 to 48 months to find a suitable candidate and costs upwards of $100 million. And in the end, roughly 95% of all potential drugs fail in clinical trials. Because of this, scientists are understandably looking for a way to speed up the discovery process.

That’s where the anti-cancer drug known as BPM 31510 comes in play. Unlike most pharmaceuticals, it was developed by artificial intelligence instead of a group of researchers toiling away in a lab. Created by biotech company Berg (named after real estate billionaire Carl Berg) the company seeks to use artificial intelligence to design cancer drugs that are cheaper, have fewer side effects, and can be developed in half the time it normally takes.

drugsTowards this end, they are looking to data-driven methods of drug discovery. Instead of generating cancer drugs based on chemical compounds identified in labs, the company compares tissue, urine, and blood samples from cancer patients and healthy patients, generating tens of trillions of data points that are fed into an artificial intelligence system. That system crunches all the data, looking for problems.

BPM 31510, which is the first of Berg’s drugs to get a real-world test, focuses on mitochondria – a framework within cells that’s responsible for programmed cell death. Normally, mitochondria triggers damaged cells to die. When cancer strikes, this process goes haywire, and the damaged cells spread. Berg’s drug, if successful, will be able to restore normal cell death processes by changing the metabolic environment within mitochondria.

MitochondriaSpeaking on the subject of the drug, which is now in human-clinical trials, Berg president and co-founder Niven Narain said:

BPM 31510 works by switching the fuel that cancer likes to operate on. Cancer cells prefer to operate in a less energy-efficient manner. Cancers with a high metabolic function, like triple negative breast cancer, glioblastoma, and colon cancer–that’s the sweet spot for this technology.

IBM is also leveraging artificial intelligence in the race to design better cancer treatments. In their case, this involves their much-heralded supercomputer Watson looking for better treatment options for patients. In a trial conducted with the New York Genome Center, Watson has been scanning mutations found in brain cancer patients, matching them with available treatments.

But, as Narain points out, the current drug discovery system desperately needs rethinking. With a success rate of 1 out of 20, their is definitely room for improvement. And a process that seeks to address cancer in a way that is more targeted, and more personalized is certainly in keeping with the most modern approaches to medicine.

News From Space: SpaceX Booster Explodes in Flight

spacex-falcon-9-octaweb-640x427Last week, during a test flight in McGregor Texas, a new space SpaceX Falcon 9 Reusable Development Vehicle 1 (F9R Dev 1) exploded in midair. This three-engine variant of the F9 is the latest in SpaceX’s arsenal of vertical takeoff, vertical landing (VTVL) rockets designed to allow for easy recovery and reuse. Previously, Grasshopper had only used a single Merlin rocket engine; but for this test, a three-engine version of the vehicle was being used.

The F9R Dev 1 is a second-generation test vehicle rocket based on the SpaceX Grasshopper. Built as part of SpaceX’s program to develop a fully reusable launcher system and spacecraft with all components capable of a powered landing, the F9R has lighter, retractable landing legs and is 50 percent longer than the Grasshopper. It made its first flight last April and is capable of flight operations up to 3,000 m (10,000 ft).

https://i0.wp.com/www.extremetech.com/wp-content/uploads/2014/08/exploding-spacex-rocket-grasshopper-f9r-640x357.jpgThis marks the first major failure for SpaceX’s commercial space launch program, and in a statement, SpaceX says the initiated its self-destruct sequence automatically after detecting an anomaly. Nearby residents saw the fireball and local television station KXXV caught the incident on video. From the footage (seen below), the new test rocket is seen going up, turning 90 degrees to horizontal, and then detonating with a rather neat fireball.

Mercifully, no one was harmed (including the local livestock). Following the incident, Elon Musk tweeted that the vehicle “auto-terminated,” but there were no injuries or near-injuries, and that “Rockets are tricky …” SpaceX also released the following statement saying:

Earlier today, in McGregor, Texas, SpaceX conducted a test flight of a three engine version of the F9R test vehicle (successor to Grasshopper). During the flight, an anomaly was detected in the vehicle and the flight termination system automatically terminated the mission.

Throughout the test and subsequent flight termination, the vehicle remained in the designated flight area. There were no injuries or near injuries. An FAA representative was present at all times.

With research and development projects, detecting vehicle anomalies during the testing is the purpose of the program. Today’s test was particularly complex, pushing the limits of the vehicle further than any previous test. As is our practice, the company will be reviewing the flight record details to learn more about the performance of the vehicle prior to our next test.

SpaceX will provide another update when the flight data has been fully analyzed.

spacex-falcon-9-rocket-largeIn short, SpaceX was attempting something new and exciting and it didn’t quite go as planned. And although it cost them millions of dollars, rocket scientists know from experience that a controlled detonation in the air is far better than an uncontrolled one on the ground. Should a rocket lose control and crash into the Earth, it will detonate all of its unspent fuel and can cause extensive damage and loss of life.

At this point it’s impossible to say what kind of anomaly was experienced by the rocket, but SpaceX is poring over the gigabytes of flight telemetry data to try and find out what went wrong. In the meantime, space enthusiasts are hoping people will remember that mishaps are part of the development process, and that we’ve come very far since the early days of NASA and Project Mercury, where mistakes and deaths were far more common.

And if SpaceX wants to create the world’s first reusable space launch system, and crack the cheap, commercial space travel market wide open, there are going to be a few fireballs along the way. But as long as it’s just the test launches that explode, we should count our blessings. And in the meantime, be sure to check out the footage obtained by KXXV of the failed test flight:
